SASH-CENTER.

Specification of Letters Patent.

Patented July 2, 1912.

Application filed October 24, 1910. Serial No. 588,839.

To all whom it may concern:

Be it known that I, ALBERT A. PAGE, a citizen of the United States of America, residing in the town of East Haven, county of New Haven, and State of Connecticut, have invented new and useful Improvements in Sash-Centers, of whiehthe following is a full, clear, and exact description, when taken in connection with the accompanying drawings, which form a part thereof.

The invention relates to sash centers, or rotary supports for windows, and consists primarily in asimple and efficient center in which a sleeve with spring pressed locking devices is rotatable with respect to a stationary core having a serrated periphery. The sleeve carries fastening plates adapted to be secured to the window or frame, and the core has fastening plates adapted to be secured to the other member. The bolts in the sleeve are adapted to engage automatically with the teeth of the core and hold the sleeve and the member to which it is secured in the position desired.

Referring to the figures, Figure 1 represents a top View of the sash center embodying this invention, Fig. 2, the same showing the sleeve turned into a different position, Fig. 3, a top view of the core or sash piece, Fig. A, a top view of the sleeve, Fig. 5, a horizontal section through the tubular sockets on the sleeve, and Fig. 6, a longitudinal vertical section of the sash center through the sockets.

In all figures, similar letters of reference represent like parts.

In the drawings, A designates a circular core with a serrated periphery B, and C the base for the core having an annular flange D. Fitted over the core is a sleeve N having an annular flange M and laterally projecting fastening plates K on which are mounted or formed integral therewith tubular sockets H. WVithin the sockets H are spiral springs retained in place by pins I and hearing at their other ends against bolts E, the extreme ends of which project through the openings 0 in the sleeve N to engage the teeth on the edge B of the core A. A shoulder E on each of the bolts E is somewhat larger in diameter than the openings O and holds the bolt within the tubular socket H. The outer ends of the tubular sockets are open and in the upper side of the fastening plates K are indentations corresponding to the curvature of the interior of the socket and in alinement with the end of the socket to permit the insertion of the bolts and springs.

The core A is provided wit-l1 laterally extending fastening plates S. The plates S are in the same horizontal plane as the fastening plates K of the sleeve, and the top of the core A is flush with the top of the sleeve N. The plates S are adapted to be secured to the window frame by screws, through screw holes T, or other suitable means, and the plates K are similarly secured by screws, through screw holes R, or other suitable means to the sash.

In operation, the expansive tendency of the springs F will constantly force the bolts E against the periphery of the core A, and when opposite one of the serrations in the periphery B the bolts will engage the serrations and yieldingly hold the sleeve from rotation. Suflicient pressure on the sash to rotate the sleeve will force the bolts E out of the serrations of the periphery B of the core A until they come opposite another serration when the springs will again shoot them forward to engage the core. By this construction, the sash may be moved from one position to another without the necessity of releasing another bolt by hand and the sash will be held in any desired position by the engagement of the spring pressed bolt with the teeth of the core A.

It will be noted that the attaching plates or straps of the two swivel members lie in a plane approximately perpendicular to the axis of the device. An attaching plate or strap for one may therefore serve as a stop to limit the movement of the other member, whereby a swinging movement of the sash or other part beyond the desired point is prevented. In the embodiment illustrated, two oppositely located laterally extending straps or fastening plates on one of the members are interposed between similarly arranged straps or fastening plates on the other member, in such a manner that the movable part will be arrested at the desired point as it moves in either direction.

Having now described my invention, what I claim and desire to secure by Letters Patent, is 2-- 1. In a sash center, a core, an attaching or fastening plate therefor lying in a plane approximately perpendicular to the axis of the core, a sleeve rotatably mounted on said core, an attaching or fastening plate for said sleeve lying in a plane approximately perpendicular to the axis of said sleeve, and a bolt carried by the sleeve and adapted to engage indentations on the periphery of the core; substantially as described.

2. In a sash center, a core having peripheral indentations, an attaching or fastening plate for said core lying in a plane approximately perpendicular to the axis of said core, a sleeve rotatably mounted with respect to said core, an attaching or fastening plate for said sleeve lying in a plane approximately perpendicular to the axis of said sleeve, and a bolt carried by the sleeve and fastening plate and adapted to engage the peripheral indentations of the core; substantially as described.

3. In a sash center, a core, a sleeve loosely embracing said core, an attaching or fastening plate for said sleeve lying in a plane approximately perpendicular to the axis of said sleeve, and a locking device to interlock the sleeve and core, carried by said plate and movable through the sleeve; substantially as described.

4. In a sash center, a core, a sleeve loosely embracing said core, laterally extending fastening plates carried by said sleeve, and locking devices mounted on the respective plates and movable through the sleeve into engagement with the core; substantially as described.

5. In a sash center, a core, a sleeve loosely embracing said core, fastening plates extendinglate'rally from said sleeve, and locking bolts carried by the respective plates and movable into engagement with the core; substantially as described.

6. In a sash center, the combination of a sleeve, a core on which said sleeve is rotatable, a fastening plate extending laterally from the sleeve, a tubular guide on said fastening plate, and a bolt in said guide projecting through the wall of the sleeve into engagement with said core; substantially as described.

7. In a sash center, core, a sleeve embracing the same, and having an opening in its wall, a fastening plate extending laterally from and formed integral with said sleeve, a tubular guide formed integral with the sleeve and with said fastening plate, and having one end registering with said opening, and a bolt in said guide having one end projecting through said opening; substantially as described.

8. In a sash center, a core, fastening means therefor, a sleeve embracing said core, a

the combination of av fastening plate extending laterally from said sleeve, and a locking bolt guided longitudinally at the upper surface of said fasten-' ing plate and having its inner end engageable with said core; substantially as described.

In witness whereof, I have hereunto set my hand on the eighth day of October, 1910.
